About the Unitree H1 Battery
The Unitree H1 battery is the official quick-release power pack for the H1 humanoid: a 15,000mAh (432Wh) lithium pack rated at DC 28.8V with a self-developed battery management system. The H1 and H1-2 run on two of these packs installed together, giving the robot 864Wh of onboard energy in total.
Each pack runs Unitree's self-developed intelligent BMS: a real-time power display on the pack itself, cell balancing, and storage self-discharge control that brings an unused pack down to a safe level on its own, backed by overcharge, over-discharge, short-circuit and load-detection protection.
With two packs doing the work, most H1 teams run a two-set rotation — one pair on the robot, one on charge — so demos, data collection and gait research keep moving through back-to-back sessions.
The Official Replacement Battery for H1 and H1-2
This Unitree H1 battery is the factory pack for the H1 humanoid family: the H1 and the H1-2 share the same battery compartment and take the same 432Wh quick-release pack. The robot is built around a two-pack architecture and requires both packs installed to operate, which is why packs are sold individually — buy one to replace the older half of an aging set, or two to fill a compartment from new.
The pack is tool-free and quick-release, so rotating the pair mid-session is a bench-side job rather than a maintenance task.

H1 Battery Life: About 1 Hour per Charge, Two Packs Onboard
The H1 is specified for about 1 hour of operation per charge from its 864Wh two-pack system. Runtime moves with the workload — continuous walking, running and dynamic demos draw more than standing poses or light development sessions — so plan sessions around a range rather than a fixed number.
Charging runs through the H1's dedicated charger at up to 9A per pack, which is what turns a two-set rotation into a practical routine.
Shipping, Quality Guarantee & Battery Care
We ship lithium batteries worldwide in UN38.3-compliant packaging via DHL or FedEx. Battery-only parcels travel as regulated air cargo, so delivery can take a few days longer than standard shipments; we confirm the exact transit time with your quote.
Every Unitree H1 battery is 100% quality-inspected before it ships, so it arrives in perfect working order. If you keep a spare in storage, the self-developed BMS automatically brings it down to a safe storage level, so the pack stays healthy between sessions.
